ABSTRACT:
A color print machine, which makes prints from developed color film, is provided with an automatic exposure control system. A memory stores control signals for adjusting the automatic exposure control system for predetermined differing color film types and is addressable for selecting the control signals to be furnished for the color film type involved. The color film is provided with machine-readable film-type identifying code markings prior to printing. A code-marking scanner performs machine-reading of the film-type identifying code markings and generates corresponding film-type signals. The memory is addressed, thereby selecting the control signals to be furnished to the automatic exposure control system for the particular color film type involved, in automatic response to the film-type signals.
